ED
Huhnseal ED is a double balanced cartridge seal maintaining sealing performance even during sudden pressure drops on the product side and/or the secondary side.The design of the seal is robust and rigid but at the same time flexible, with excellent radial and axial movement capabilities.The springs are located outside both the product and the flush minimizing risk for clogging.
1 Excellent axial movementThe seal can move ± 2,0 mm independent of the compression of the springs. The seal follows the movement of the shaft without influencing the compression of the springs. This feature is essential when sealing equipment with flexible bearing units.
2 Patented protected spring packageThe springs are located outside both the product and the flush. Minimizing the risk for clogging, which is one of the most common causes for seal failure. Patent No: 900912-2
3 Safe drive of rotating surface at the atmospheric sideThe rotating face on the atmospheric side is driven by three big drive pins machined into the sealing face. The pins are not in contact with the quench liquid, eliminating the risk of them being blocked axially by residues from the quench.
4 Excellent radial movement capabilitiesThrough a new design the seal is able to compensate for angular deviation without generating stresses over the seal faces, which may influence sealing performance. This feature minimizes the effects of excessive shaft bending during operation against closed valves.
5 Hygienic applicationsSmooth surfaces without cavities or closed spaces make the seal suitable for food and drug applications. If required, the gasket may be replaced with O-rings according to EHEDG in order to achieve a hygienic designed seal suitable for CIP (Cleaning in Place).
6 H4 designThe rotating sealing face on the product side has the new “H4-design”. This means that the seal face is O-ring mounted and the outer diameter of the seal face is the same as of the holder. This prevents the forming of turbulent flows, which cause heavy wear in abrasive liquids.
7 Axial cooling channelsAllow for installation of a double seal in applications with very limited space.

ES
Huhnseal ES is a balanced single mechanical seal with a unique and modern design. The springs are not placed directly behind the stationary face, this being the most common competitor solution, but have been located on a larger diameter further away fom the critical O-ring and seal face gap in order to reduce risk for clogging. Due to the relocation of the springs, more robust springs may be used enabling to change from compression to tension springs. The robust tension spring design gives the seal better performance since it is more difficult for particles and fibers from the product to reach and clog up the springs. Additionally the relatively long springs with larger wire diameter increase the axial and radial movement capabilities of the seal.First-class materials from carefully selected suppliers ensure optimized perfor-mance at minimized built-in dimensions.
1 Hygienic solutionsSmooth surfaces without cavities or closed spaces make the seal suitable for food and drug application. If required the gasket may be replaced with O-rings in execution according to EHEDG to achieve a hygienic designed seal suitable for CIP (Cleaning in Place).
2 Excellent angular movement capabilitiesAdvantage when operating against closed valves, causing shaft bending.
3 H4 designThe rotating sealing face on the product side has the new “H4-design”. This means that the seal is O- ring mounted and the outer diameter of the seal face is the same as of the holder. This prevents the forming of turbulent flows, which cause heavy wear in abrasive liquids.
4 Advantageous built-in dimensionsFits in most standard pump stuffing boxes.
5 Optional additional flange for flushingThe seal may be equipped with an extra flange when flushing into the media is needed. The standard design is without flange since the chamber with a small gap given by the flushing flange may encourage material build-up if flush is not connected.
6 Spring package located on the outside of the flangeThis design is better protected against fiber and par-ticle build-up, which eventually causes clogged- up springs.
7 Patented tension springsAllow for an excellent axial movement of ± 2,0 mm.Patent No: 9803436-6
The axial built-in measurement increases with19 mm irrespective of the shaft dimension.
